Title: Photothermal displacement measuring apparatus
Inventor: MORIMOTO TSUTOMU
IPC: G01N29/00
Filed: 1995-03-08
Abstract: PURPOSE: To measure the photothermal displacement regardless of the surface conditions of a sample. CONSTITUTION: When the photothermal displacement of a sample 5 is measured using a measuring light 6 obtained by irradiating the sample 5 with an exciting light 3, the measuring part of the sample 5 is irradiated with ultraviolet rays 12 having predetermined energy, independently from the exciting light 3 and the measuring light 6, by means of an ultraviolet lamp 10 and an optical fiber 11. With such arrangement, the photothermal displacement can be measured regardless of the surface conditions of the sample.

Title: Radio direction detector
Inventor: OKAZAKI MORIHIRO
IPC: G01S3/28
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To eliminate a scale of a device by a method wherein a signal selecting circuit measures a relative simplification and phase of reception signals from a plurality of aerial line elements in time sharing by two receivers and calculates a direction. SOLUTION: A reception signal of a channel which is the maximum in electric-field strength level measurement among an aerial line elements 1 is input to a signal selecting circuit 5 and is input to a first radio direction finder receiver 6. A reception signal of three channels other than the channel which is the maximum in electric-field strength level measurement is input to a second radio direction finder receiver 6 sequently from the signal selecting circuit 5. A signal processor 9 references a channel of a reception signal input to the first radio direction finder receiver 6, and obtains data of phase slippages and simplification slippages of the respective remaining reception-base channels. Correction data are added, and relative phases and simplification differences between correct first to n-th channels are calculated.  An arrival direction of signals is calculated by a digital beams homing technique from the relative phases and simplification differences data.

Abstract: PURPOSE:To simplify the structure of the title device and, at the same time, to improve the operability of the device by constituting a device which adjusts plural kinds of volumes, such as volumes of ringing tones, speeches, etc., of memories which cope with plural kinds of operations at every operation, a single adjusting means which increases and decreases the contents of the memories, and control means which discriminates the state of each operation and selects a memory to be adjusted. CONSTITUTION:When an up-switch 31 or down-switch 32 in an automatic telephone set 20 is operated at the time of operating a key-switch group 22, the volume of confirmation sounds is changed by increasing or decreasing the storing content of the storing section 49a of a RAM 49. On the other hand, when the switch 31 or 32 is operated in a called state, the volume of the ringing tone is adjusted by increasing or decreasing the storing content of a storing section 49b. In case when the switch 31 or 32 is operated in a state where a call is carried on in a hand-free state, the volume of the receiving sound of a loudspeaker 29 is adjusted by increasing or decreasing the content of a storing section 49c. Similarly, a loudspeaker 26 is adjusted by increasing or decreasing the storing content of a storing section 49d and, when the content of the RAM is changed, a displaying section 27 is caused to make a display corresponding to the change.

Title: Synchronizing signal processing circuit for picture printer
Inventor: NAGATA TOMISUKE
IPC: H04N1/36
Filed: 1990-02-28
Abstract: PURPOSE:To prevent a succeeding normal input signal from being eliminated by adding a pseudo synchronizing signal to a position with a missing synchronizing signal through self-excitation oscillation at no input state when the synchronizing signal is missing and using a noise elimination circuit to limit the input signal till lapse of a prescribed time. CONSTITUTION:When a horizontal synchronizing signal S11 including noise signals N1, N3 and a missing part N2 of the synchronizing signal is inputted to a retriggerable multivibrator 11, only the edge of the horizontal synchronizing signal S11 is valid to the multivibrator 11 and a pulse S12 with a sufficiently short setting time is outputted. However, when the synchronizing signal is missing (N2), an output of a retriggerable multivibrator 10 goes to logical 1 after lapse of a prescribed time and a pseudo synchronizing signal is outputted to a position of missing synchronizing signal. In this case, since an additional circuit 4 triggers a retriggerable multivibrator 16, an AND gate element 12 is closed by a prescribed time t10. Thus the noise N3 after the pseudo synchronizing signal is added is eliminated.

Filed: 1990-02-28
Abstract: PURPOSE:To improve the efficiency of a communication office work by warning the operator with a warning tone or warning display when a detection means confirms unloading of a recording medium by the operator after the end of picture recording and an incomplete document is included in the recording medium. CONSTITUTION:When the end of a picture data is confirmed, an alarm circuit 12 is driven to inform it to the operator that a recording medium whose picture recording is finished is discharged to a stacker 2. Then a main control section 7 controls a recording medium detection circuit 11 to light a light emitting element 5 thereby checking the output state of a photodetector 6. When the recording medium 4 is not extracted and the photodetector 6 does not receive light, till the recording medium 4 is extracted, the detection is continued. When the recording medium 4 is extracted and an incomplete document caused due to a communication error is included in the extracted recording medium 4, the alarm circuit 12 is driven and the presence of the communication error is noticed to the operator in voice.

Title: Skip prevention device for toothed belt
Inventor: YAMAGUCHI MUTSUYUKI
IPC: F16H7/02
Filed: 1986-03-05
Abstract: PURPOSE:To normally apply a small tension, but apply a large tension when a rapid change in load occurs, by contacting two pulleys with a back surface of a toothed belt for a bicycle or the like, connecting rotating shafts of the pulleys with each other by an arm, and making the arm rotatable about its fulcrum shaft. CONSTITUTION:When a pedal 1 is strongly depressed under the condition where a proper tension is preliminarily applied to a toothed belt 3, an upper side portion of the toothed belt 3 is stretched, while a lower side portion is slackened. As a result, a belt tooth 3a tends to run onto a pulley tooth 4a, causing a skip on the slackened side, especially, on a driven pulley 4 side. That is assuming a height of the pulley tooth 4a is delta, the toothed belt 3 tends to outwardly urge a first pulley 6 by the amount of delta and resultantly apply a clockwise moment to an arm 8. Accordingly, a second pulley 7 is moved to be pressed onto the toothed belt 3 to increase the tension of the belt 3, thereby preventing the skip. Accordingly, it is sufficient to normally apply a small tension to the toothed belt 3.

Abstract: PURPOSE:To determine whether the number of persons existing near the boundary of a main zone is one or two, by performing a detection both in a main zone and an auxiliary zone when an adjacent zone overlap-detection circuit detects that human beings exist near the boundary of the main zone. CONSTITUTION:The presence and the position of human beings in a main zone which were already detected with a detection element 15 and memorized into a memory circuit 19 by the output of a comparator 18 are inputted into an adjacent zone overlap-detection circuit 22 to determine whether a human being exists at the same array position of an adjacent main zone as viewed in extension of the main zone detected. The circuit 22 starts to operate when detecting the presence of a human being at the position in the same array and closes a normally open contact 22a while opening a normally closed contact 22b. The ANDing of the presence of a human being in the main zone and the presence of a human being at the position in the same array is obtained with an AND circuit 23 from a memory circuit 14 for auxiliary zone and the memory circuit 19 for main zone and the results are outputted to an output circuit 25 through an OR circuit 24. Thus, it is possible to determine whether one or two persons exist near the main zone boundary.
